Description

The present invention relates to a gate device that restricts passage of vehicles and the like at a tollgate of a highway or a toll road, or at an entrance/exit of a parking lot, and more particularly, to a gate device that automatically returns a released gate bar.

BACKGROUND ART Conventionally, a gate device is installed, for example, at an ETC (Electronic Toll Collection System) gate at a toll gate on an expressway or a toll road, or at the entrance/exit of a toll parking lot. The gate device regulates the passage of the vehicle by causing the gate bar to lie down (closed) to block the road. Normally, the vehicle does not collide with a gate bar that blocks the road. However, for example, when a vehicle illegally passing through the ETC gate or a vehicle that forgets to install an ETC card in the ETC vehicle-mounted device passes through the ETC gate, or a vehicle exiting from the exit of the parking lot intentionally or by mistake, the gate bar When traveling without waiting for opening, a vehicle may collide with the gate bar. Some gate devices rotate (release) the gate bar in the vehicle traveling direction when the vehicle collides, in order to prevent damage to the gate bar due to the collision of the vehicle. In addition, there is a gate device that automatically or remotely controls the released gate bar.

For example, Patent Document 1 discloses a vehicle passage breaker that prevents inadvertent rotation of a blocking rod in a normal state and quickly and easily returns the blocking rod after a release operation. This vehicle passage breaker is a breaker equipped with a blocking rod supported by an arm via a release shaft, and further includes a return drive for rotating the blocking rod in a released state toward a normal state. Part, stopper means provided on the arm and biased toward the blocking rod in the normal state, and an engagement position provided on the blocking rod and engageable with the stopper means when the blocking rod is in the normal state A pedestal that can be moved back and forth between a retracted position and a retracted position, and a pedestal moving means that positions the pedestal at the engaged position in the normal state and positions the pedestal in the retracted position in the released state. And,

Further, for example, Patent Document 2 discloses a blocking rod breakage reporting system and a blocking rod breakage reporting method for shortening the time from the occurrence of breakage of the blocking rod to the recognition of the breakage of the blocking rod by a staff member at a security office. Has been done. This breaker rod breakage notification system is a system that notifies the security office that the breaker rod of the breaker has broken, and the breaker monitors the condition of the breaker rod and detects when the breaker rod is broken. A monitoring unit that outputs a failure information signal, and a transmission unit that transmits the failure information signal as an electromagnetic wave to the security center. The security center includes a receiving unit that receives the fault information signal transmitted as an electromagnetic wave from the transmitting unit, and an alarm unit that issues an alarm according to the fault information signal. The transmission unit and the reception unit transmit/receive a failure information signal by wireless communication using an ad hoc network.

In the automatic release type gate device used for ETC gates on expressways and toll roads, as described above, after the vehicle collides with the gate bar and the gate bar is released in the traveling direction of the vehicle, the gate bar is automatically returned. I am letting you. Although the gate bar rarely breaks or breaks with only one collision, the gate bar may gradually deform due to repeated collision and release and release return several times, which may cause large deformation or breakage. .. If the gate bar is clearly bent on the outside, it may be possible to detect abnormality of the gate bar even with a surveillance camera, etc., but since the gate bar is constructed by covering the periphery of the core material with a cushioning material, Deformation or damage cannot be detected from the appearance. For example, even if the cushioning material is not damaged in appearance, cracks or the like may occur in the core material. In such a state, when the vehicle collides with the gate bar, the core material is completely broken before the gate bar is released, the cushioning material is also broken at a moment, and a part of the gate bar or broken pieces, There is a risk of splashing on that lane or another adjacent lane. Further, such a damage of the gate bar may cause a secondary accident in the worst case.

In the vehicle passage breaker disclosed in Patent Document 1, when the lane server determines an abnormal vehicle and performs an abnormal process, the arm is maintained at the blocking position, and thus the vehicle may collide with the blocking rod. At this time, the blocking rod is released. The return operation of the blocking rod after the completion of the release operation is performed based on, for example, a release return command sent by an operation of the operation unit by a staff member at the tollgate. Then, the control device rotates the output shaft of the return motor in the return drive unit in the forward direction, the first rotation support shaft connected to the output shaft rotates, and the pressing bar rotates in the return direction accordingly. At this time, the pressing portion provided at the tip of the pressing bar that rotates in the returning direction contacts the pusher plate. When the pressure bar further rotates in the return direction, the pressing force of the pressing portion is transmitted to the blocking rod via the pusher plate, and the pusher plate and the blocking rod rotate in the return direction, so that the blocking bar returns. Be seen. However, in Patent Document 1, deformation, damage, breakage, etc. of the released blocking rod are not considered at all.

In the breaking rod breakage reporting system of Patent Document 2, the breaking portion of the breaking rod is detected by the monitoring unit monitoring the electric current of the conductor provided on the breaking rod, the pressure and the sound of the pipe of the breaking rod, and the failure information signal. Is output to the transmitter of the circuit breaker. In this case, it is necessary to connect the monitoring unit on the blocking rod side and the transmitting unit on the blocking unit side by electrical wiring or the like. However, when such a configuration is applied to a device that realizes the release operation and the release return operation of the gate bar (blocking rod), such as the vehicle passage breaker of Patent Document 1, when the configuration is applied to the gate bar of the monitoring unit. It becomes difficult to arrange the wiring and wiring between the monitoring unit and the transmission unit. Further, the electric wiring between the monitoring unit and the transmission unit may be tensioned by the release operation and the release return operation of the gate bar, and may be broken in some cases.

The present invention has been made in view of the problems as described above, and an object of the present invention is to detect an abnormality of the gate bar early while mounting an automatic mechanism for the release return operation of the gate bar, and to break the gate bar.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are preferred specific examples of the present invention and disclose various preferable techniques, but the technical scope of the present invention is not limited to these aspects.

First, a gate device 1 according to an embodiment of the present invention will be described. As shown in FIG. 1 and the like, the gate device 1 is made of concrete formed along the road 2 at the side of the road 2 at the gate of a toll gate of a highway or toll road or the entrance of a toll parking lot. It is installed on Island 3 which is the platform of. The gate apparatus 1 regulates the passage of a gate of a vehicle (moving body) traveling on the road 2 by opening and closing a gate bar 16 described later. The surface of the gate device 1 on the side of the road 2 and the curb portion of the island 3 on the side of the road 2 are preferably as close as possible, and the closer the distance is, the shorter the length of the gate bar 16 is. it can.

In the present embodiment, for convenience of description, when the gate is viewed from a point before passing through the gate on the road 2, the front side is “front”, the other side (back side) is “rear”, and the right side is “right”. , The left side is defined as “left”, the upper side is defined as “upper”, and the lower side is defined as “lower”. Hereinafter, when the direction is described in the present embodiment, this definition is followed. A vehicle traveling on the road 2 usually approaches the gate apparatus 1 from the front of the gate apparatus 1 and then proceeds to the rear of the gate apparatus 1. That is, the front-back direction of the gate device 1 is a vehicle traveling direction (moving body traveling direction) parallel to the road 2.

The gate device 1 is orthogonal to the main body portion 11 and a rotary portion 13 rotatably provided above the main body portion 11 via a vertical rotary shaft 12 extending in the vertical direction and the vertical rotary shaft 12. A gate bar base 15 rotatably provided on the rotary unit 13 via the horizontal rotary shaft 14 and a gate bar 16 detachably attached to the gate bar base 15 so that a releasing operation described later can be performed.

Note that the position of the rotating portion 13 when the horizontal rotating shaft 14 is positioned so as to extend in the front-rear direction is referred to as a “lane-blockable position” (FIG. 1, FIG. 3 (1) and (2), FIG. 4(1) and (2), see FIG. 6(2)). Further, in the operation of returning the released gate bar 16 (release return operation), the position of the rotating portion 13 when the gate bar 16 is held by the gate bar base 15 (the horizontal rotating shaft 14 is positioned so as to extend in the left-right direction). The position of the rotating portion 13 at this time) will be referred to as a "gate bar approaching position" (see FIG. 3(4), FIG. 5(2), and FIG. 6(1)). In the following, each direction in the description of each part such as the rotating part 13 is shown with reference to the lane-breakable position, unless otherwise specified.

Further, when the rotating portion 13 is at the position where the road can be blocked (normal position), the horizontal rotating shaft 14 is rotated so that the gate bar base 15 and the gate bar 16 lie down and stand up. The operation of blocking/opening is referred to as "road opening/closing operation" (or gate opening/closing operation). At this time, a position where the gate bar base 15 and the gate bar 16 lie down is referred to as a “recumbent position” (see broken lines in FIG. 1, FIG. 3(1), and FIG. 4(1)), and a position where the gate bar base 15 and the gate bar 16 stand upright. This is referred to as the "standing position" (see the solid line in FIG. 4(1) and the solid line in FIG. 6(2)). Hereinafter, each direction in the description of the gate bar base portion 15, the gate bar 16 and the like is shown with reference to the recumbent position unless otherwise specified.

First, the main body 11 will be described. The main body 11 includes a main body housing 21 formed in a rectangular column shape, and the main body housing 21 is fixed on the island 3. An opening/closing lid 17 is attached to the rear surface of the main body housing 21 so as to be openable and closable, and when the opening/closing lid 17 is opened, a rear opening formed in almost the entire rear surface of the main body housing 21 opens. It is like this.

The main body 11 includes a vertical rotation shaft 12 inside a main body housing 21, and a rotation drive unit 22 that rotationally drives the vertical rotation shaft 12. The vertical rotation shaft 12 is disposed substantially in the center of the main body housing 21, and the upper end of the vertical rotation shaft 12 is exposed to the outside through an opening formed in the substantially upper center of the main body housing 21. , Can be connected to the rotating unit 13.

The rotary drive unit 22 includes a rotary drive motor 55 (see FIG. 2) and the like described later. The rotary drive unit 22 rotates the vertical rotary shaft 12 in the horizontal direction to move the rotary unit 13 connected to the vertical rotary shaft 12 together with the horizontal rotary shaft 14, the gate bar base 15, and the gate bar 16. It can be rotated horizontally. For example, the rotation drive unit 22 rotates the vertical rotation shaft 12 when returning the released gate bar 16 to the state before the release operation, that is, the original state in which the road opening/closing operation is possible.

Further, on the left rear side of the main body housing 21, a stop portion 23 (stopper) that supports the released gate bar 16 is provided. The restraint portion 23 stands on the mounting arm 24 at a position spaced rearward from the main body housing 21. The mounting arm 24 extends rearward from the main body housing 21. The restraint portion 23 is composed of, for example, a vertically long shaft portion 23a and a rotary roller 23b rotatably provided around the shaft portion 23a.

Further, the main body unit 11 includes the power transmission unit 25 on the left side of the main body housing 21. In the normal state, the power transmission unit 25 is arranged near the stopping unit 23 on the mounting arm 24 at a position separated from the power receiving unit 26 provided on the gate bar 16. On the other hand, in the power transmission unit 25, for example, when the rotation unit 13 is rotated to the gate bar approaching position and the gate bar 16 is held by the gate bar base 15, the power reception unit 26 provided in the gate bar 16 approaches and faces each other.

The power transmission unit 25 is connected to a power supply (not shown) of the gate device 1, and when the power reception unit 26 approaches the power transmission unit 25, power is wirelessly supplied to the power reception unit 26 (power is supplied in a contactless manner). To). That is, the power transmission unit 25 and the power reception unit 26 form a non-contact power feeding unit. The non-contact power feeding unit including the power transmission unit 25 and the power receiving unit 26 is configured to supply power by an electromagnetic coupling method and perform signal transmission as a non-contact communication unit, for example. When the power receiving unit 26, which is a transmission unit having a power receiving coil and the like, enters the transmittable region of the power transmitting unit 25, which is an output unit having the power transmission coil and the like, electromotive force is generated in the power receiving unit 26 by electromagnetic coupling. In this way, power is supplied from the power transmission unit 25 to the power reception unit 26. Further, the power transmission unit 25 and the power reception unit 26 form a non-contact communication unit, and the power transmission unit 25 receives the detection signal transmitted from the power reception unit 26.

Next, the rotating unit 13 will be described. The rotating unit 13 includes a box-shaped rotating casing 31 formed in a rectangular column shape. When the gate device 1 is viewed from above, the rectangular outer shape of the rotary housing 31 is substantially the same as the rectangular outer shape of the main body housing 21, and the vertical shape is approximately at the center of the lower surface of the rotary housing 31. It is connected to the rotary shaft 12. An opening/closing door (not shown) is attached to the rear surface of the rotating housing 31 so that the opening/closing door can be opened and closed. Is becoming

The rotating unit 13 includes a horizontal rotating shaft 14 inside the rotating housing 31, and a gate bar driving unit 32 for rotating the horizontal rotating shaft 14 together with the gate bar base 15 and the gate bar 16. The tip of the horizontal rotation shaft 14 is exposed to the outside through an opening formed in the front surface of the rotation housing 31 and can be connected to the gate bar base 15. A flange 33 is fixed to the tip of the horizontal rotation shaft 14 for detachably attaching the gate bar base 15 with a screw or the like.

The gate bar drive unit 32 includes a gate bar drive motor 52 (see FIG. 2) described later and the like. The gate bar driving unit 32 keeps the horizontal rotating shaft 14 at the gate bar base 15 and the gate bar 16 while the rotating unit 13 is positioned so that the road can be blocked and the horizontal rotating shaft 14 extends in the front-rear direction. The vehicle can be opened/closed by rotating the same together (see FIG. 4(1)). For example, the gate bar driving unit 32 opens the road 2 so that the gate bar base 15 and the gate bar 16 are in the “recumbent position” (see the chain double-dashed line in FIG. 4(1)) when the road 2 is blocked. When doing so, the horizontal rotation shaft 14 is rotated so that the gate bar base 15 and the gate bar 16 are in the "standing position" (see the solid line in FIG. 4(1)). The “upright position” of the gate bar base 15 and the gate bar 16 may be a position that sufficiently opens the road 2 (gate). For example, a position in which the gate bar base 15 and the gate bar 16 are vertically erected or The position may be upright at about 85 degrees.

Next, the gate bar base 15 and the gate bar 16 will be described. The gate bar base 15 is a long member having a U-shaped cross section with an opening on the front side, and has a shape in which one end side of the gate bar 16 is fitted. The rear surface of the gate bar base 15 on one end side (right side) in the longitudinal direction is attached to the horizontal rotation shaft 14, and is rotatable with respect to the rotation unit 13 in accordance with the rotation of the horizontal rotation shaft 14. There is. On the other hand, the other end side (left side) in the longitudinal direction of the gate bar base 15 extends in a direction intersecting with the horizontal rotation shaft 14 (a direction orthogonal to the horizontal rotation shaft 14 in the present embodiment). Further, a release rotation shaft 41 extending in the lateral direction (vertical direction) is provided on the other end side of the gate bar base 15. An opening 26 a for exposing the power receiving portion 26 provided on the gate bar 16 is formed on the rear surface of the gate bar base 15.

Further, in the gate bar base 15, a torsion spring 42 as a release urging portion is mounted around the release rotation shaft 41 (see FIG. 3(1)). The torsion spring 42 applies an urging force to the gate bar 16 so as to promote the rotation of the gate bar 16 in the release direction during the release operation.

The gate bar 16 is formed in a long shape and has a length that can block the road 2 when the passage of a vehicle is restricted by one gate device 1. When the two gate devices 1 are arranged on the left and right sides of the road 2, the gate bar 16 is formed relatively short. The gate bar 16 includes a gate bar holding portion 43 provided on one end side (right side) in the longitudinal direction, and a gate bar main body 44 attached to the gate bar holding portion 43 and extending to the other end side (left side) in the longitudinal direction.

The gate bar body 44 of the gate bar 16 is formed by covering the other end side of a core material 44a made of a light weight material, for example, aluminum and a hollow square pipe with a cushioning material 44b made of urethane foam or the like (FIG. 8). The core material 44a of the gate bar main body 44 is provided with a large number of thinned square holes 44c at regular intervals. The square hole 44c is formed to reduce the weight of the core material 44a, and is a surface along the vehicle traveling direction (when the rotating portion 13 is at the position where the road can be blocked and the gate bar 16 is at the lying position). It may be provided on the (upper and lower surfaces), and may also be provided on the surfaces (front and rear surfaces) facing each other in the vehicle traveling direction. The outer surface of the cushioning material 44b is preferably laminated with a red-white stripe or the like in order to improve visibility from a driver or the like. The gate bar main body 44 is replaced by inserting/removing a portion of the core material 44a on the right end side of the gate bar main body 44, which is not covered with the cushioning material 44b, from the left side in the longitudinal direction of the gate bar holding section 43 along a guide (not shown). After being inserted into the gate bar holding portion 43, a cover 43a covers and locks a locking mechanism 45 described later, but the cover 43a is omitted in FIGS. 3 to 6.

The gate bar 16 is attached to the gate bar base 15 so that the gate bar holding portion 43 fits into the gate bar base 15. At this time, the other end in the longitudinal direction of the gate bar holding portion 43 located in the middle portion of the gate bar 16 is rotatably supported by the release rotation shaft 41 of the gate bar base 15. As a result, the gate bar 16 can be rotated around the release rotation shaft 41 with respect to the gate bar holding portion 43.

One end of the gate bar 16 is detachably held on one end of the gate bar base 15. Specifically, the locking mechanism 45 is provided on one end side of the gate bar base 15 and one end side of the gate bar 16, and the locking mechanism 45 allows the one end side of the gate bar base 15 and the one end side of the gate bar 16 to be connected. Removably locked to each other. For example, as shown in FIG. 8, the locking mechanism 45 includes a locking portion 45a provided on one end side of the gate bar base portion 15 and a latch 45b provided on one end side of the gate bar holding portion 43 of the gate bar 16. ..

The gate bar base 15 and the gate bar 16 are linearly extended and integrally fixed by being locked by the locking mechanism 45, so that the vehicle can be opened and closed. When the locking mechanism 45 releases the gate bar base 15 and the gate bar 16, the integrated fixing is released, and the gate bar 16 rotates about the release rotation shaft 41 with respect to the gate bar base 15. In the present embodiment, this rotation operation is referred to as a “release operation”, and the release operation causes the gate bar 16 to rotate around the release rotation axis 41 (the gate device 1 arranged on the island 3 on the right side of the road 2). In this case, the other end in the longitudinal direction of the gate bar 16 is the direction toward the vehicle traveling direction, and the clockwise direction when viewed from above) is referred to as the "release direction" (see the broken line arrow in FIG. 3(2)).

The locking mechanism 45 has a holding force sufficient to maintain the locking between the gate bar base portion 15 and the gate bar 16 (gate bar holding portion 43) even if a force such as vibration or wind pressure due to the road opening/closing operation is applied. .. On the other hand, the locking mechanism 45 allows the locking between the gate bar base 15 and the gate bar 16 (gate bar holding part 43) to be released by a force greater than the holding force, for example, an external force applied when the vehicle collides with the gate bar 16. Composed. The locking mechanism 45 locks the gate bar base 15 and the gate bar 16 when the released gate bar 16 rotates in the non-release direction and is fitted into the gate bar base 15 by a predetermined pressing force. Have.

In addition, the gate bar 16 includes a deformation detection unit 46 that detects the degree of deformation such as breakage of the core material 44a of the gate bar main body 44, as shown in FIGS. The deformation detection unit 46 includes, for example, a first conductive tape 46a and a second conductive tape 46b having conductivity, and an energization detection unit 47.

The first conductive tape 46a is attached to the front inner surface and the rear inner surface of the core material 44a of the gate bar main body 44, which are opposed to each other in the vehicle traveling direction, over the entire area in the longitudinal direction of the gate bar main body 44. The second conductive tape 46b is attached to the other end (left side end) of the core material 44a while electrically connecting the front and rear first conductive tapes 46a to each other. In other words, the front and rear first conductive tapes 46a and the second conductive tape 46b have both ends on one end side (right side) of the core material 44a and are attached to the core material 44a over the entire inner circumference. Make up a pattern. Therefore, if the front and rear first conductive tapes 46a and the second conductive tape 46b are not torn, the conductive state of the conductive pattern can be confirmed on one end side of the core material 44a. On the other hand, when the first conductive tape 46a or the second conductive tape 46b is torn at any place, the conductive state of the conductive pattern cannot be confirmed at one end side of the core material 44a. , Abnormal conduction of the first conductive tape 46a and the second conductive tape 46b is detected.

Further, a reinforcing tape 44d is attached to the outside of the core material 44a of the gate bar main body 44 over the entire area in the longitudinal direction. The reinforcing tape 44d is a high-strength thin film adhesive tape reinforced with glass fiber or the like, and has extremely high tensile strength. On the other hand, the first conductive tape 46a is a tape which is not so high in tensile strength and has little stretchability. Therefore, if the core material 44a of the gate bar main body 44 breaks when the vehicle collides with the gate bar 16, the first conductive tape 46a also breaks accordingly, but the reinforcing tape 44d prevents the core material 44a from being completely broken. Separation is prevented. Further, by attaching the first conductive tape 46a and the reinforcing tape 44d to different surfaces (on the inner surface and the outer surface) of the core material 44a, respectively, while improving the detection sensitivity of breakage, separation after breakage is performed. It can be prevented as much as possible.

The gate bar holding part 43 of the gate bar 16 is provided with the power receiving part 26 and the energization sensing part 47 described above. The power reception unit 26, which constitutes the contactless power supply unit, is activated by receiving power supply from the power transmission unit 25 and supplies power to the energization detection unit 47. In addition, the power reception unit 26 that constitutes the non-contact communication unit transmits the detection signal from the energization detection unit 47 to the power transmission unit 25.

The power receiving unit 26 is arranged on the front surface side of the gate bar holding unit 43 (the side on which the release rotation shaft 41 is provided), for example, near the release rotation shaft 41. The power receiving unit 26 is a power transmitting unit 25 installed in the vicinity of the stopping unit 23 of the gate device 1 during normal times when the rotating unit 13 is in the position capable of blocking the road (see FIG. 3A, FIG. 4A, etc.). And are separated from each other. However, in the release return operation, there is a state in which the power receiving unit 26 and the power transmission unit 25 are extremely close to each other to stop (see FIG. 3(4), FIG. 5(2), etc.), and this approaching state is controlled by the stop unit 23. Since the positioning is performed while suppressing the vicinity of the base of the gate bar 16, reproducibility is extremely improved.

The energization sensing unit 47 includes a contact portion 47a connected to one end (right end) of each of the front and rear first conductive tapes 46a provided on the core material 44a of the gate bar main body 44, and a contact holding portion that holds these contact portions 47a. It has a portion 47 b and an electric wiring 47 c connected to the power receiving portion 26. Then, the energization sensing unit 47 senses the conduction of the first conductive tape 46a and the second conductive tape 46b provided on the core material 44a of the gate bar body 44, and outputs a sensing signal of the sensing result (sensing result). It is configured to output to the power receiving unit 26.

For example, the energization sensing unit 47 is provided with a direct current 2-wire type contact switch in the contact holding unit 47b, and if the resistance value between the contact units 47a is 0, it is determined to be conductive and detection indicating OK (ON). A signal is output, and if the resistance value between the contact portions 47a is equal to or higher than a predetermined threshold value (most are infinite), it is determined to be non-conductive and a detection signal indicating NG (OFF) is output. Each contact portion 47a may be configured, for example, as a plug-in connector that sandwiches the core material 44a of the gate bar 16 from the inside and the outside. Alternatively, each contact portion 47a may be configured such that a commercially available detachable connector is provided on the gate bar holding portion 43 side and the gate bar main body 44 side, and they are connected by fitting both.

According to the configuration of the energization sensing unit 47, even if the gate bar 16 is rotated about the release rotation shaft 41 with respect to the gate bar base 15, tension is not applied to the electric wiring 47c and the like. Since the power receiving unit 26 and the power transmission unit 25 do not face each other, the energization sensing operation is not performed, while the energization sensing operation is performed only during the release return operation.

Next, the release operation and the release return operation in the gate device 1 will be described with reference to FIGS. 3 to 6 show the release operation and the release return operation of the gate device 1. Here, the “release return operation” is an operation of returning the gate bar 16 that has been released to the state before the release operation, that is, the original state in which the road opening/closing operation is possible.

First, the release operation of the gate device 1 will be described. In the gate device 1, normally, as shown in FIG. 3(1), FIG. 4(1), etc., the rotating portion 13 is at the position where the road can be blocked, and the horizontal rotating shaft 14 extends in the front-rear direction. Are arranged so that the vehicle can be opened and closed by the gate bar base 15 and the gate bar 16.

In a normal state, the vehicle does not collide with the gate bar 16 that blocks the road 2. However, for example, in a normal state where a vehicle that has forgotten to install an ETC card in an ETC (Electronic Toll Collection System) vehicle-mounted device passes through the gate of the ETC, the vehicle may be blocked by the gate bar 16 that blocks the roadway 2. May collide.

When a vehicle traveling along the road 2 collides with the gate bar 16 that blocks the road 2, the vehicle collides with the other end side of the gate bar 16 (the other end side of the gate bar main body 44). When the vehicle collides with the gate bar 16 in this manner, the locking mechanism 45 is unlocked by an external force applied to the other end side of the gate bar 16 due to the collision, and one end side of the gate bar base 15 (gate bar 16 One end side of the holding portion 43) is detached. Then, as shown in FIG. 3(2), FIG. 4(2), etc., the gate bar 16 rotates in the vehicle advancing direction (release direction) about the release rotation shaft 41 (FIG. 3(2) dashed arrow). reference).

At this time, when the force applied to the other end side of the gate bar 16 due to the collision is small, the gate bar 16 is rotated by the force due to the collision and the biasing force of the torsion spring 42 provided near the release rotation shaft 41. Then, it hits the stopping portion 23 with a comparatively weak force to stop. As described above, according to the torsion spring 42, the gate bar 16 that performs the releasing operation can reach the stopping portion 23 reliably and quickly, and the state in which the gate bar 16 hits the stopping portion 23 and stops can be maintained. On the other hand, when the force applied to the other end side of the gate bar 16 due to the collision is large, the gate bar 16 pivots vigorously due to the force due to the collision and hits the blocking portion 23 with a relatively strong force. The shock received is absorbed by the cushioning material 44b and the like of the gate bar 16. In this way, the gate bar 16 rotates, for example, about 90 degrees clockwise (release direction) and stops, the direction of the gate bar 16 becomes substantially parallel to the road 2, and the release is completed.

Next, the release return operation of the gate device 1 will be described. The release operation of the gate bar 16 as described above is detected by a release detection switch 58 (see FIG. 2) described later, and in response to this, the control unit 50 (see FIG. 2) immediately starts the release return operation automatically. To be done. In the release return operation, first, as shown in FIG. 3C and FIG. 5A, the rotation drive unit 22 rotates the vertical rotation shaft 12, and the rotation unit 13 releases the gate bar 16. It is rotated so as to follow or follow the rotation of. For example, the rotation drive unit 22 rotates the rotation unit 13 by about 90 degrees in the clockwise direction (release direction) from the position where the road can be blocked to the gate bar approaching position (FIGS. 3(4) and 5(2)). reference).

At this time, the gate bar 16 also rotates in the clockwise direction with the rotation of the rotating unit 13 (see FIGS. 3(3) and 5(1)). Since the gate bar 16 is in contact with the stopper 23, the gate bar 16 slides backward while the contact with the stopper 23 is maintained while the rotating portion 13 rotates in the clockwise direction. Become. Then, the gate bar 16 pivots in the non-releasing direction around the release pivot shaft 41 with the contact portion with the restraining portion 23 as a fulcrum, so that the restraining portion 23 extends from the intermediate portion in the longitudinal direction of the gate bar 16 to the one end side. While gradually tracing the rotating roller 23b, one end side of the gate bar 16 (one end side of the gate bar holding portion 43) approaches the one end side of the gate bar base portion 15.

As shown in FIG. 3C, while the rotating portion 13 is rotating, the other end of the gate bar 16 slightly moves in the direction away from the road 2, and the direction of the gate bar 16 is parallel to the road 2. However, if the other end of the gate bar 16 interferes with another device installed on the island 3 at this time, the distance from the main body 11 of the stopper 23 should be increased. Thus, the portion of the gate bar 16 near the other end abuts on the stop portion 23. As a result, the amount of movement of the other end of the gate bar 16 in the direction away from the road 2 can be reduced, so that the other end of the gate bar 16 can be prevented from interfering with other devices.

Then, as shown in FIG. 3(4) and FIG. 5(2), when the rotating portion 13 rotates to reach the gate bar arrival position, one end side of the gate bar 16 (one end side of the gate bar holding portion 43) is moved to the gate bar. The one end side of the base 15 and the one end side of the gate bar base 15 and the one end side of the gate bar 16 are pressed in the clockwise direction by the force of the rotation drive part 22 to rotate the rotating part 13. Further, one end of the gate bar 16 receives elastic force from a holding spring (not shown) at the bottom of the gate bar base 15. At this time, the force of the rotation drive unit 22 and the force of the holding unit spring, which are in opposite directions to each other, act on one end side of the gate bar base 15 and one end side of the gate bar 16, so that they are strong in the direction of approaching or contacting each other. Pressed. As a result, the locking mechanisms 45 provided on one end side of the gate bar base 15 and one end side of the gate bar 16 are reliably locked to each other. By this locking, the gate bar base portion 15 and the gate bar 16 are integrally fixed so that both of them face the same direction.

In this way, when the rotating portion 13 rotates to the gate bar approaching position and one end side of the released gate bar 16 is locked (held) to the one end side of the gate bar base portion 15, the rotation drive portion 22 becomes The rotation of the rotation unit 13 is stopped.

Subsequently, as shown in FIG. 6(1), the gate bar driving unit 32 rotates the horizontal rotation shaft 14 to rotate the gate bar base 15 and the gate bar 16 upward (FIG. 6(1) broken line arrow). reference). At this time, the directions of the gate bar base 15 and the gate bar 16 that are integrally fixed are still parallel to the road 2. Then, when the gate bar base portion 15 and the gate bar 16 which rotate upward are in the upright position, the gate bar drive unit 32 stops the rotation of the horizontal rotation shaft 14.

Thereafter, as shown in FIG. 6(2), the rotation drive unit 22 rotates the rotation unit 13 in a direction (non-release direction) opposite to the traveling direction (release direction) of the vehicle (FIG. 6(2)). ) See dashed arrow). Then, when the rotating portion 13 reaches the position where the road can be blocked, the rotation driving portion 22 stops the rotation of the rotating portion 13. For example, the rotating unit 13 rotates counterclockwise (non-release direction) by about 90 degrees to reach the lane-blockable position. In this way, when the rotating portion 13 reaches the position where the road can be blocked, the position of the gate bar 16 becomes the same as the position when the road 2 is opened in the road opening/closing operation, and therefore the release return operation is performed as it is. The release return operation may be completed after the gate bar 16 is further rotated to the lying position. When the release return operation is completed after rotating the gate bar 16 to the recumbent position, it is judged whether there is a vehicle passing through the gate for safety before the gate bar 16 is rotated. Only when there is no vehicle passing through the gate, the gate bar 16 is rotated to the lying position.

Next, the electrical configuration of the gate device 1 will be described with reference to FIG. FIG. 2 shows a configuration for electrically controlling the operation of the gate device 1.

The gate device 1 includes a control unit 50 for integrally controlling the gate device 1, an abnormality determination unit 51 for determining whether or not there is an abnormality in the gate bar 16, a gate bar drive motor 52 for rotating the gate bar base 15, A first limit detection switch 53 for detecting that the gate bar base 15 or the gate bar 16 has reached the lying position, and a second limit detection switch 54 for detecting that the gate bar base 15 or the gate bar 16 has reached the standing position, A rotation drive motor 55 that rotates the rotation unit 13, a third limit detection switch 56 that detects that the rotation unit 13 has reached the position where the road can be blocked, and the rotation unit 13 moves to the gate bar arrival position. A fourth limit detection switch 57 for detecting arrival, a release detection switch 58 for detecting establishment/release of the integrated fixing of the gate bar base 15 and the gate bar 16, a control program for right installation, and a control for left installation. A setting operation unit 59 capable of setting operations such as switching to and from a program, and a communication unit 60 for communicating with a road control device 70 outside the gate apparatus 1 and the like are provided.

The control unit 50 is provided in the main body housing 21 of the main body unit 11 and includes a CPU (Central Processing Unit) 50a and a memory 50b, and the CPU 50a and the memory 50b are connected via a bus 50c. The memory 50b includes a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk, a flash memory, and the like, and stores programs and data for controlling the gate device 1. The memory 50b stores, for example, a control program that controls the road opening/closing operation, the release return operation, and the like of the gate apparatus 1. The CPU 50a reads a program or data stored in the memory 50b and executes the program to control the road opening/closing operation, the release return operation, and the like of the gate apparatus 1. The bus 50c is further connected to the interface 50d.

The control unit 50, via the bus 50c and the interface 50d, the above abnormality determination unit 51, the gate bar drive motor 52, the first limit detection switch 53, the second limit detection switch 54, the rotation drive motor 55, the third. The limit detection switch 56, the fourth limit detection switch 57, the release detection switch 58, the setting operation section 59, and the communication section 60 are connected. The control unit 50 is also connected to the power transmission unit 25, controls the power supply of the power transmission unit 25, and receives a signal transmitted to the power transmission unit 25.

The abnormality determination unit 51 determines whether or not there is an abnormality in the gate bar 16 in the state of the gate bar 16 approaching the main body 11 after the release operation in the course of the release return operation. The abnormality determination unit 51 determines the abnormality of the gate bar 16 based on, for example, the detection result of the deformation detection unit 46, and specifically, the detection result of the energization detection unit 47 indicates the first conductive tape 46a and the second conductive tape 46a. When the conductive tape 46b becomes non-conductive, the deformation of the core material 44a of the gate bar 16 is detected. The abnormality determination unit 51 may be configured by a program that is executed by the control unit 50 and performs the above abnormality determination process.

The gate bar drive motor 52 and the rotation drive motor 55 are, for example, DC motors. Release detection switch 58 is, for example, mounted in the axial hole of the horizontal pivot axis 14, and ON when OFF, is both away when the gate bar base 15 and the gate bar holding portion 43 is sufficiently close or contact Become. The setting operation unit 59 is, for example, a DIP switch, and is provided inside the main body housing 21. The communication unit 60 is provided in the main body housing 21, and is transmitted from the ETC antenna (not shown) to the road control device 70 outside the gate device 1 when the gate device 1 is installed in an ETC gate, for example. The received vehicle data is received from the road control device 70.

Next, in the gate apparatus 1, the control of each unit by the control unit 50 in the release return operation of the gate bar 16 that has performed the release operation as described above will be described with reference to the flowchart of FIG. 7.

First, in the gate apparatus 1, when the vehicle collides with the other end side of the gate bar 16 while the gate bar 16 is closing the road 2 while the road is being opened or closed, or when the vehicle is in the recumbent position, the gate bar base 15 and The integrated fixing with the gate bar 16 is released, and the gate bar 16 performs a release operation of rotating in the release direction. When the integrated fixing of the gate bar base 15 and the gate bar 16 is released, the release detection switch 58 is turned on (step S1: YES).

When the release detection switch 58 is turned on, the control unit 50 drives the rotation drive motor 55 to rotate the vertical rotation shaft 12 in the clockwise direction (as viewed from above) (step S2). By rotating the vertical rotation shaft 12 in the clockwise direction in this way, the rotation portion 13 at the roadway blockable position rotates in the traveling direction of the vehicle (the release direction of the gate bar 16).

Then, when the rotating unit 13 reaches the gate bar approaching position, the fourth limit detection switch 57 is turned on (step S3: YES). When the rotating portion 13 reaches the gate bar approaching position in this way, the gate bar 16 is locked to the gate bar base portion 15 as described above, and integrated fixing is established between the two, and the release detection switch 58 is turned off. (Step S4: YES). Immediately after this, the control unit 50 stops the rotation drive motor 55 (step S5).

In this way, when the gate bar 16 approaches the main body 11 in the process of the release return operation, the abnormality of the gate bar 16 is determined (step S6). In this state, since the power transmission unit 25 and the power reception unit 26 that form the contactless power supply unit are close to each other, power is supplied from the power transmission unit 25 to the power reception unit 26, and the power reception unit 26 and the energization detection unit 47 are to start. Then, as the abnormality determination of the gate bar 16 by the control unit 50, the energization sensing process is performed by the energization sensing unit 47, and the abnormality determination unit 51 determines the abnormality of the gate bar 16 based on the sensing result of the energization sensing unit 47. If the sensing result of the energization sensing unit 47 is in the conductive state (OK) (step S6: YES), the abnormality determination unit 51 determines that the gate bar 16 is not abnormal, and proceeds directly to step S8. On the other hand, if the result of sensing by the energization sensing unit 47 is the non-conducting state (NG) (step S6: NO), the abnormality determination unit 51 determines that the gate bar 16 is abnormal and informs the abnormality determination (step S7). ). For example, in step S7, an abnormality is notified to the road control device 70 outside the gate device 1 or a monitoring center (not shown) via the communication unit 60. After that, the release return operation is continued, and the process proceeds to step S8.

In step S8, the controller 50 rotates the gate bar drive motor 52 in the clockwise direction (as viewed from the tip end side of the horizontal rotation shaft 14). The clockwise rotation of the gate bar drive motor 52 causes the gate bar base 15 and the gate bar 16 in the recumbent position to rotate toward the standing position. When the gate bar base 15 and the gate bar 16 reach the standing position, the second limit detection switch 54 is turned on (step S9: YES). Immediately after this, the control unit 50 stops the gate bar drive motor 52 (step S10).

Subsequently, the control unit 50 drives the rotation drive motor 55 of the rotation drive unit 22 to rotate the vertical rotation shaft 12 in the counterclockwise direction (as viewed from above) (step S11). Rotation of the vertical rotation shaft 12 in the counterclockwise direction causes the rotation portion 13 at the gate bar approaching position to rotate in the direction opposite to the traveling direction of the vehicle (the release direction of the gate bar 16). Then, when the rotating portion 13 reaches the position where the road can be blocked, the third limit detection switch 56 is turned on (step S12: YES). Immediately after this, the control unit 50 stops the rotation drive motor 55 (step S13).

Subsequently, the control unit 50 determines whether or not the road 2 can be blocked (step S14). For example, when the control unit 50 receives a signal indicating that the vehicle cannot be blocked or the vehicle is approaching from the road control device 70 outside the gate apparatus 1, the control unit 50 determines that the vehicle cannot be blocked, and does not receive such a signal. Is determined to be shut off.

When it is determined that the road 2 can be closed (step S14: YES), the control unit 50 rotates the gate bar drive motor 52 counterclockwise (as viewed from the tip end side of the horizontal rotation shaft 14) ( Step S15). The counterclockwise rotation of the gate bar drive motor 52 causes the gate bar base 15 and the gate bar 16 in the standing position to rotate toward the recumbent position. Subsequently, when the gate bar base 15 and the gate bar 16 reach the lying position, the first limit detection switch 53 is turned on (step S16: YES). Immediately after this, the control unit 50 stops the gate bar drive motor 52 (step S17). This completes the release return operation.

As described above, according to the present embodiment, the gate device 1 that restricts the passage of the vehicle (moving body) on the road 2 includes the main body portion 11, the gate bar base portion 15, the gate bar 16, and the gate bar driving portion 32. And a release return mechanism including the rotating unit 13 and the stopping unit 23, and an abnormality determining unit 51. The gate bar base portion 15 is located above the main body portion 11, one end side of which is supported by the main body portion 11 so as to be rotatable around a horizontal rotation shaft 14 extending in the horizontal direction, and the other end side thereof is horizontally rotated. It is configured to extend in a direction intersecting with the moving shaft 14. The gate bar 16 is supported such that an intermediate portion thereof is rotatable on the other end side of the gate bar base portion 15 around a release rotation shaft 41 extending in a direction intersecting the extension direction of the gate bar base portion 15, and one end side of the gate bar base portion 15 is supported. It is detachably held on one end side, and the other end side is configured to extend in the same direction as the gate bar base 15. The gate bar driving unit 32 rotates the gate bar base 15 between a recumbent position where the gate bar base 15 and the gate bar 16 are lying down and an upright position where the gate bar base 15 and the gate bar 16 are upright. Composed. In the release return mechanism, in a state where the gate bar base 15 is positioned so as to block the road 2 by the gate bar 16 in the recumbent position, one end side of the gate bar 16 is separated from one end side of the gate bar base 15 and the gate bar 16 releases the rotation axis. After performing a release operation of rotating around 41 in the release direction toward the moving direction of the vehicle, a release return operation of holding one end side of the gate bar 16 at one end side of the gate bar base 15 is performed. The abnormality determination unit 51 is provided in the main body unit 11 and configured to determine whether or not the gate bar 16 has an abnormality in the state where the gate bar 16 is close to the main body unit 11 after the release operation in the process of the release return operation. To be done.

With such a configuration, in the gate device 1 that automatically performs the release operation from the release operation, it is possible to determine abnormality such as breakage, deformation, and damage of the gate bar 16 in conjunction with the release operation. Further, since the state where the gate bar 16 is close to the main body portion 11 is used after the release operation, the reproducibility is good, and the comparison between the previous state and the current state of the gate bar 16 can be optimized. It is possible to make a stable judgment of abnormality.

In addition, the gate device 1 according to the present embodiment is provided with a non-contact power feeding unit including a power receiving unit 26 provided on the gate bar 16 side and a power transmitting unit 25 provided on the main body unit 11 side, and a non-contact power feeding unit provided on the gate bar 16 side. A deformation detection unit 46 is further provided, which is activated by receiving power supplied from the power supply unit and detects deformation of the core material 44a of the gate bar 16. The power reception unit 26 and the power transmission unit 25 are configured to be capable of contactless communication with each other, and transmit the detection result of the deformation detection unit 46 to the abnormality determination unit 51. The abnormality determination unit 51 determines the abnormality of the gate bar 16 based on the detection result by the deformation detection unit 46.

With such a configuration, when the gate bar 16 approaches the main body 11 in the release return operation of the gate bar 16, the deformation of the core material 44a of the gate bar 16 is detected by using the non-contact power supply and the non-contact communication. You can Therefore, it is not necessary to provide an electric wire having low durability between the gate bar 16 and the main body 11 or an expensive and heavy battery in the gate bar 16, and the deformation detection of the gate bar 16 can be realized at low cost. be able to.

In addition, in the gate device 1 according to the present embodiment, the deformation detecting unit 46 includes the conduction pattern including the first conductive tape 46a and the second conductive tape 46b arranged along the extension direction of the gate bar 16, and the conduction pattern. And a current-carrying sensing unit 47 that senses the conductive state of the conductive pattern by electrically connecting with the conductive pattern and detects the deformation of the core material 44a of the gate bar 16 when the conductive pattern becomes the non-conductive state.

With such a configuration, the deformation of the gate bar 16 can be detected with a low cost and a simple configuration.

In addition, in the gate device 1 according to the present embodiment, the release return mechanism of the gate bar 16 includes the rotating portion 13, the stopping portion 23, and the rotation driving portion 22. It is supported by the main body 11 so as to be rotatable around a vertical rotation shaft 12 that is located above and extends in the vertical direction, and is configured to rotatably support a horizontal rotation shaft 14. .. The stopping portion 23 is arranged on the rotation trajectory of the gate bar 16 during the release operation. The rotation drive unit 22 determines the position of the rotation unit 13 so that the gate bar 16 in the recumbent position blocks the road 2 when restricting the passage of the vehicle. On the other hand, when performing the release return operation, The rotating portion 13 is rotated so as to follow the rotation of the gate bar 16 so that one end side of the gate bar 16 approaches or contacts one end side of the gate bar base portion 15, and one end side of the gate bar is one end side of the gate bar base portion 15. It is configured to determine the position of the rotating portion 13 so as to hold it.

With such a configuration, in the release return operation, the rotation drive unit 22 rotates the rotation unit 13 to bring the gate bar 16 close to the main body unit 11 while suppressing the gate bar 16 by the stop unit 23. It is possible to maintain good reproducibility of the approaching state between the main body 11 and. As a result, the accuracy of detecting the abnormality of the gate bar 16 can be improved.

In addition, in the gate device 1 according to the present embodiment, the power transmission unit 25 is provided near the stopping unit 23.

With such a configuration, when the gate bar 16 is automatically released and returned, the power transmitting unit 25 and the power receiving unit 26 can be stably brought close to each other and a stable non-contact power feeding state can be maintained.

In addition, in the present embodiment, the gate device 1 has been described as the configuration including the rotating portion 13 and the stopping portion 23 as the release return mechanism that performs the release return operation of the gate bar 16, but the release return mechanism is limited to this configuration. Not done. For example, in another embodiment, the release return mechanism of the gate bar 16 includes a return drive unit (not shown) such as a return drive arm that rotates the released gate bar 16 around the release rotation shaft 41 in a non-release direction. No.) may be included in the gate bar base 15.

In the present embodiment, the deformation detecting portion 46 provided on the gate bar 16 side for detecting the deformation of the gate bar 16 includes the first conductive tape 46a and the second conductive tape 46b provided on the core material 44a of the gate bar main body 44 and the gate bar. Although the example of the configuration including the energization sensing unit 47 provided in the holding unit 43 has been described, the deformation sensing unit 46 is not limited to this. For example, in another embodiment, as shown in FIG. 9, the deformation detection unit 46 outputs an inspection signal such as a sound wave (ultrasonic wave) or light to the inside of the core material 44 a of the gate bar main body 44, the inspection signal output unit 61. And a reflected signal receiving unit 62 that receives a reflected signal such as a reflected sound or reflected light with respect to the inspection signal.

The inspection signal output unit 61 is provided in the gate bar holding unit 43 and outputs an inspection signal from one end side of the gate bar main body 44. The reflection signal receiving unit 62 is provided in the gate bar holding unit 43, and receives the reflection signal of the inspection signal reflected inside the core material 44a and reaching the one end side of the gate bar main body 44. That is, the inspection signal output unit 61 and the reflected signal reception unit 62 form a nondestructive inspection device. When the deformation detection unit 46 including the inspection signal output unit 61 and the reflection signal reception unit 62 is applied, the normality obtained by using the normal gate bar 16 at the time of shipment of the gate device 1 or the start of use of the gate bar 16 is obtained. The reflected signal is stored in the memory 50b of the control unit 50 in advance. After that, when the release return operation is performed, for example, the inspection signal output unit 61 and the reflected signal reception unit 62 are operated at the timing of step 6 in the flowchart shown in FIG. 7. Then, the abnormality determining unit 51 compares the reflection signal obtained by the reflection signal receiving unit 62 with the normal reflection signal stored in the memory 50b, and if they are significantly different, determines that the gate bar 16 has an abnormality.

As described above, according to another embodiment, in the gate apparatus 1, the deformation detection unit 46 includes the inspection signal output unit 61 and the reflection signal reception unit 62, and outputs the inspection signal from the one end side of the gate bar 16 into the gate bar 16. It is configured to output the signal, receive the reflected signal of the inspection signal, and detect the deformation of the core material 44a of the gate bar 16 based on the reflected signal.

With such a configuration, the deformation detection of the gate bar 16 can be realized by another configuration that is low cost and simple.

In the present embodiment, the gate device 1 has the configuration in which the deformation detecting unit 46 is provided on the gate bar 16 side in order to determine the abnormality of the gate bar 16, but the configuration is not limited to this. For example, in another embodiment, as shown in FIG. 10, in the gate apparatus 1, in addition to the deformation detection unit 46, or instead of the deformation detection unit 46, the stopping unit 23 receives from the gate bar 16 during the release return operation. A strain sensing unit 63 is provided on the main body unit 11 side as a pressure sensing unit that senses a pressing force. When the gate device 1 includes the strain sensing unit 63 instead of the deformation sensing unit 46, the contactless power feeding unit including the power transmitting unit 25 and the power receiving unit 26 may be omitted.

The strain sensing unit 63 measures the load (load) applied to the shaft portion 23a of the restraining portion 23 by the gate bar 16 pressing the restraining portion 23, and is composed of, for example, a strain gauge that detects the strain of the shaft portion 23a. To be done. The strain sensing section 63 is arranged below the restraining section 23 in the mounting arm 24, and is connected to the control section 50 via electric wiring. The detection result of the strain sensing unit 63 is transmitted to the control unit 50, and the abnormality determination unit 51 connected to the control unit 50 determines the abnormality of the gate bar based on the detection result of the strain sensing unit 63.

During the release return operation, the gate bar 16 gradually moves while tracing the rotary roller 23b of the stopping portion 23 from the intermediate portion to the one end in the longitudinal direction as shown in FIGS. 3(2) to (4). At this time, the strain values detected by the strain sensing unit 63 are output with almost the same tendency (within a predetermined normal range) in the case of the normal gate bar 16 without deformation. However, when the gate bar 16 is damaged and the core material 44a of the gate bar main body 44 is deformed, cracked, or damaged, the strain value detected by the strain sensing unit 63 is output with a tendency different from that of the normal gate bar 16. For example, the distortion value becomes extremely large or small, or the distortion value extremely changes during the release return operation. If the strain value detected by the strain sensing unit 63 is within a predetermined normal range, the abnormality determining unit 51 determines that the gate bar 16 is normal (OK), and the strain sensing unit 63 tends to be different from normal. If the strain value of 1 is detected, it is determined that the gate bar 16 is abnormal (NG). In the case where the gate device 1 is configured to include the deformation sensing unit 46 and the strain sensing unit 63, either the AND condition or the OR condition of the sensing result of the deformation sensing unit 46 and the sensing result of the strain sensing unit 63 is used. Although it is possible to judge whether the gate bar 16 is abnormal, it is safest and preferable to judge that the gate bar 16 has an abnormality when either one is NG.

FIG. 11 shows an example of strain data detected by the strain sensing unit 63 as described above. In this example, the strain sensing unit 63 detects the strain of the shaft portion 23a of the restraining portion 23 caused by the pressing of the gate bar 16 from the release operation to the release return operation. In FIG. 11, the strain data 101 detected in the case of the normal gate bar 16 is shown by a solid line, and the strain data 102 detected in the case of a damaged gate bar 16 is shown by a broken line. The normal strain data 101 changes somewhat depending on the thickness of the cushioning material of the gate bar 16 and the length of the gate bar 16. Further, since the normal strain data 101 also changes depending on the strength of the torsion spring 42, it often indicates a different value for each gate device 1. Therefore, when the gate device 1 is shipped or when the gate bar base 15 or the gate bar 16 is initially used, the normal strain data 101 for each gate device 1 is measured and stored in the memory 50b of the control unit 50 in advance.

In the initial stage of the release operation, the gate bar 16 vigorously hits the stop portion 23 due to the collision of the vehicle, and thus the strain data rises to the extent that the scale-out occurs once, but immediately ends and returns to around 0 again. After that, when the release return operation is started, the normal strain data 101 starts to gradually rise from the timing when the gate bar 16 comes into contact with the stop portion 23, the rotation drive motor 55 stops, and the rotation portion 13 moves. It peaks when it reaches the gate bar pickup position.

In this embodiment, in the release recovery operation, when the abnormality of the gate bar 16 is judged in step 6 of the flowchart shown in FIG. 7, the strain data obtained by the strain sensing unit 63 greatly changes from the normal strain data 101. The abnormality determination unit 51 monitors whether or not to do so, that is, whether or not it is within the normal range based on the normal strain data 101. The normal range is determined by setting an allowable range above and below the normal strain data 101, for example. For example, when the core material 44a of the gate bar main body 44 is significantly deformed, as shown in FIG. 9, the strain sensing unit 63 outputs strain data 102 that largely deviates from the normal strain data 101. In this way, when the degree of difference between the waveforms of the strain data 102 being monitored and the normal strain data 101 is large, the abnormality determination unit 51 determines that the gate bar 16 has an abnormality (step 6: YES). As a result, although the gate bar 16 is not broken, the significantly deformed core material 44a can be detected.

As described above, according to another embodiment, the gate device 1 further includes the strain sensing unit 63 as a pressure sensing unit that is provided on the main body unit 11 side and that senses the pressure force that the restraining unit 23 receives from the gate bar 16. The abnormality determining unit 51 has a predetermined strain data (pressing force) as a detection result of the strain detecting unit 63 when the rotating unit 13 rotates and the gate bar 16 presses the stopping unit 23 during the release return operation. When it is out of the normal range, it is determined that the gate bar 16 is abnormal.

With such a configuration, it is possible to determine the abnormality of the gate bar 16 while moving the gate bar 16 along the longitudinal direction while making contact with the stop portion 23, and to strengthen the function of preventing damage to the gate bar 16 in advance. You can

According to the gate apparatus 1 of the present invention configured as described above, it is easy to judge the damage or deformation of the gate bar 16 to be released by the ETC gate or the like which automatically performs the release return operation. Further, even when the damage or deformation cannot be visually confirmed, the damage or deformation of the core material 44a inside the cushioning material 44b can be detected. Therefore, it is possible to appropriately determine the replacement time of the gate bar 16, and it is possible to replace the gate bar 16 that is severely damaged or deformed before damage or breakage occurs.

Further, the present invention can be appropriately modified without departing from the scope or spirit of the invention that can be read from the claims and the entire specification, and a gate device with such a modification is also within the technical concept of the present invention. included.
